Question

F1=8N
F2=15N
find resultant

explain please full solution
dont span​

Answer 1

Explanation:

The question does not clarify the direction of force. Hence there will be 2 answers. If both the forces are in the same direction, add them. If the are in opposite direction, subtract them.

Answer 2

Answer:

see..either the angle could be zero(minimum) or could be 180°(maximum)

resultant = ranging from possibilites of angle 0 to 180

(A+B).. to...(A-B)

as the cos@ varies..

F1+F2=8+15=23N

F1-F2=15-8=7N

so the answer will not be less than 7..and not be greater than 23..

so the only which goes correct is..

22N

hope it helps!
